title: The relationship between aminopyrine breath test and severity of liver disease in cirrhosis.
abstract: Twenty-two patients with cirrhosis were evaluated by the 2 hr.-(C14)-aminopyrine breath test, the conventional liver tests and two systems for grading the severity of liver disease. Twenty-three patients with noncirrhotic liver disease and 15 controls were also studied. Reduced 14CO2 values were found in 21 of the 22 cirrhotic patients and seven of those had noncirrhotic liver disease associated with severe functional reserve impairment. The values in patients with minor liver diseases or cholestasis were normal. In the cirrhotic patients 2 hr.-(C14)-aminopyrine breath test scores correlated with prothrombin time, retention of bromosulfalein, fasting serum bile acid, albumin, bilirubin, serum aspartate aminotransferase and, above all, with the scores of the two clinical rating systems. The 2 hr.-(C14)-aminopyrine breath test was superior to conventional tests in quantifying the degree of hepatic functional reserve and forecasting the prognosis.
